Ant / Javacsript : copy trouble
Hi, I'm trying to use an Ant copy task in a snippet of javascript code.
the <copy> task works well when I call it in normal "ANT" syntax, but when I
call the "copy" task in javascript, it throws a NullPointerException on the
execute() method.
I wonder if there is a problem with the FileSet class because it founds no
file to copy, whereas the ant fileset task copies 49 files.
Here is my buildfile and the output of the debug below.
Thanks for helping.
By the way, I'm using the copy task in JavaScript because I need to loop

Re: Ant / Javacsript : copy trouble
Posted by peter reilly <pe...@corvil.com>.
You are missing a couple of setProjects.
The following example works: (using createTask("copy")
instead of a direct new Copy(), createTask also sets
the project on the task).
<target name="t">
<delete quiet="yes" dir="export"/>
<mkdir dir="export"/>
<script language="javascript">
importPackage(Packages.org.apache.tools.ant.types);
importClass(java.io.File);
fs = new FileSet();
fs.setProject(project);
fs.setDir(new File("."));
fs.setIncludes("build.xml");
c = project.createTask("copy");
c.setTodir(new File("export"));
c.addFileset(fs);
c.execute();
</script>
</target>
